HASH CHAINS
A chain-of-custody log that cannot be quietly edited. Every entry is hashed onto the one before it — change, delete or reorder anything after the fact and verification names the exact broken link. Ship the export as a receipt nobody can tamper with.

EXAMPLE FLOW — prove you did not touch the evidence
- you create a chain named seized-laptop-2026 before you touch anything.
- you append: #1 'powered on, photographed screen, no disk encryption prompt'.
- every action gets its own entry — imaging, hashing, handoff to a colleague, who signed what.
- them opposing counsel alleges you edited the log months later.
- you open /chain — the integrity column says verified: all links re-hash clean.
- you export the JSON receipt; anyone can re-run the sha256 chain and reach the same verdict.
HOW IT WORKS
- Each entry stores only its data, a timestamp and hash = sha256(chain-seed, entry#, time, data, previous-hash).
- The first entry is anchored to a random per-chain seed; every later entry is anchored to the hash before it.
- Editing any historical entry changes its hash — which breaks the hash of everything after it, so the tamper point is pinpointed, not just detected.
- Verification re-walks the whole chain on page load: intact chains show a green verdict, tampered ones name the first bad entry number.
- Export produces a JSON receipt with every entry + hash. Keep a copy offline; it will verify against the live chain forever — or expose any drift.
- Use one chain per distinct item or matter. Dense, boring, contemporaneous entries are the whole point.
